Usual modal analysis techniques are based on the Fourier transform. Due to the ∆T.∆f limitation, they perform poorly when the modal overlap μ exceeds 30%. A technique based on a high-resolution analysis algorithm and an order-detection method is presented here, with the aim of filling the gap between the lowand the high-frequency domains (30% < μ < 100%). A pseudo-impulse force is applied at po...

The detailed comparative analysis of luminescent and scintillation properties of the single crystalline films (SCF) of YAG:Ce garnet grown from melt-solutions based on the traditional PbO-based and novel BaO-based fluxes, and of a YAG:Ce bulk single crystal grown from the melt by the Czochralski method, was performed in this work. Using the Am (a-particle, 5.49 MeV) excitation we show that scin...

BACKGROUND Multiplexed amplicon melting is a closed-tube method for genotyping that does not require probes, real-time analysis, asymmetric PCR, or allele-specific PCR; however, correct differentiation of homozygous mutant and wild-type samples by melting temperature (T(m)) analysis requires high-resolution melting analysis and controlled reaction conditions. METHODS We designed 4 amplicons b...

magnesium alloys in liquid-phase condition form surface oxide films due to their high rate of oxidation. oxide films enter the melt as a result of surface turbulence, and remain inside the workpiece after solidification. the incoherent nature of their interface causes decreases in mechanical properties and reliability of castings. the effect of critical velocity and greater velocities of enteri...

background: tuberculosis is one of the infectious diseases worldwide that has resurgence by the aids epidemic and led to the rise of drug-resistant tuberculosis patients. thus, it seems essential to monitor the drug susceptibility in tuberculosis patients. the new high resolution melting (hrm) method is simple, rapid and inexpensive for detection of the mutations responsible for drug resistance...

this is a report on the study of high melt flow, highly isotactic polypropylene homopolymer synthesized in liquid monomer using a fifth generation ziegler-natta catalytic system. at highest catalyst productivity, the response of thecatalyst to hydrogen as chain transfer is studied. melt flow rate is controlled by hydrogen as chain transfer from 0.4 to 300 g/10min with changing the amount of hyd...
